Application April 20, 1927, Serial-N0. 1

:is invention relates to hnprm'enicnts -nbiug machines, and r to theteed motion for "bloble 'llhe usual teed motion consists of a trip arm0; er ted by inclines or come from the part of ti o comb, which armcarries a y .i vl to operate a toothed wheel, which in turn moves therollers, the wool being drawn to the COHll) by means of boxes and gearconnected therewith. l find that this arrange ment is not entirelysatisfactory, due to the we' it of material causing a tendency for amovement opposite in direction to the feed movement.

invention is in the nature at a rack ably operated to move a pinionwhich in turn operates a worm which engages and operates a worm wheel inconnection with the rollers. his gives a positive teed, not subject toback lash, and obviates the use of the usual inclines.

T18 teeth on the rack may be made variable to suit the desired feed, andthe teeth of pinion will be constant, but in an alternative form theteeth of the pinion may be variable as to teeth and the rack beconstant.

Referring to the drawings which form part of this specification Fig. 1represents a sectional elevation of a comb with my invention appliedthereto.

Fig. 2 represents a plan.

Fig. 8 represents an elevation of an alternative form of construction.

Fig. represents a plan of the niechanisni shown in F1. 0.

F 5 and 6 re resent details of a moditieil 'l'orin of rock hereinafterreferred to.

To carry my invention into ell'ect and with rotor-once to the 'awingswhich illustrate a convenient method of construction and modificationsthereof, 1 wish it to be understood that I may further vary the details,so lo g as I operate the rollers F by means of a re :1: and piniondevice actuating a worm wheel motion.

The existing castings and brackets or hangers of a Noble comb will beused where possible, filing, boring, or adding to 52111713 as may betound necessary.

the form illustrated in fl and 2, suitable and rnreiterably adjustablebracket A mounted in connection with the j l: v a rack in this caseconnieinbei rt carrying pegs lit readdctachahle in. order that thelength of 85,189, and in Great Britain June 23,

rack may be varied to alter the feed. The member it maybe moved in orout or the bracket A and the bracket A may be raised or lmvered to suitvarying requirements.

he rack will engage a suitable wheel such whcelti carried on a shaft- Swhich L carried by a bracket H. attached "-l The shaft S the usualhangers i.

i rain; Res in er carries in a suitable position a worzn which engages aworm wheel ably carried from a bracket or bearing attached to the hangerH or bracket H. This worm wheel will have a preferably square boss 53which will be engageable by a squared end F of the rollers F, one geartwo rollers and giving to the same a re feci motion with freedom frombaclr lash.

As before mentioned the teeth of llllQJiLCli may be varied as tonumberand the rack be variable to length but alternatively I may use thewheel S as a change wheel and alter the number and pitch of teeththerein.

R ferring to Figs. 8 and a, in this form the rack mechanism comprises aspring box it carried by the bracket A and springs 18. will contact witha rack plate R which in turn will carry a rack R made in one or moreportions. lhis rack will operate a wheel in the nature of a spin wheel53* carried on the shatt S the other portions being as heretoforedescribed.

Figs. 5 and 6 show a further modification of a rack device carried bythe bracket A and con'iprising a bot-z like device It carried by fixablepinions R The box like device may have any suitable number of equal orsubstantially equal sides, each side or face carryinga rack ofdi'llerent length to enable to i is of a change to be quickly made, aset screw It being provided to fix the desired rack in position.

it will be seen that in addition to obtaining a constant and positiveteed, such feed or traverse may be quickly and easily changed, eitherby, in some forms, changing the star and spur wheel and leaving the rackconstant, or by changing the rack, and while ll prefer one motion tooperate two rollers F, in some cases each roller may be operatedindependently. here two rollers are operated at once two racks per combwill be sulficicnt.

What l claim is:

i. In a feed motion for the teed rollers O'ii Noble combs, thecombination of rotatable team 5 iii;

3. A feed motion for the feed rollers of Noble combs, comprising incombination,

a rotatable frame, a normally stationary, adjustable rack, a Wheelcarried by said frame and adapted to contact with and be driven by therack as the frame rotates, feed rollers mounted for rotation in saidframe, a worm driven by said Wheel, and a Worm Wheel in onefl'fifll'lfilll; therewith and engaging the arbors of said feed rollersfor imparting a positive 'l'eell motion thereto.

4:. A feed motion for the feed rollers ol Noble combs, comprising incombination, a rotatable frame, a stationary rack, a removable wheelcarried by said frame and adaptec'l to contact with and be driven by therack as: the frame rotates, feed rollers mounted for rotation in saidframe, and

' WO1J11 gearingbetween said wheel and the arbor-s of said feed rollersfor in'lparting a positive feed motion thereto.

In testimony \i hereof' I have signed my name to this sjieeil'ieation.
